摘要： PURPOSE:To monitor the state of objective facilities high precision and accuracy by extracting and comparing respective components of the frequency, phase, and amplitude of a physical signal generated by the facilities with a judgement reference. CONSTITUTION:The start of analysis is indicated through a keyboard 5 after the setting of analytic condition is completed. Data fk which is passed through filters 11 and 21 at a cutoff frequency and a sampling frequency set by an adapter 25 on the basis of the rotational frequency of a dust collecting fan, A/D-converted by converters 12 and 22, and quantized is inputted to an arithmetic device 2 through an interface 10. The device 2 stores the signal fk in an external storage device 3 successively and temporarily and then calculates and displays respective components of the frequency, phase, and amplitude on a display device 4 while recording them in the device 3. Those components are used to decide the state of the object of monitoring according to the decision reference.

摘要： PURPOSE:To set accelerometers as specified readily and accurately and to measure the vibration of a conduit line simply and accurately, by keeping the upper surface of a supporting table always horizontal. CONSTITUTION:Wire rope is attached to a wire engaging part 14 so that the tip of an output shaft 12 of an air cylinder is located at the inner side from the outer surface of a case 1. A device is inputted at a specified measuring position in a conduit line 16. At this time, a supporting table 3 is fixed to the case 1. An unwinding device 15 is attached to the wire engaging part 14. The supporting table 3 serves the role of a weight. Therefore, the upper surface of the supporting table 3 becomes approximately horizontal. Whether the supporting table 3 is horizontal or not is verified by a potentiometer 10. When the table is inclined, the device is corrected by moving it slightly in the direction of the axis of the conduit line. After the device is inputted to the specified measuring position, the air cylinder 13 is actuated, the output shaft 12 is protruded outward, and the inner wall of the conduit line 16 is pushed. Since the air cylinder 13, a supporting shaft 5 and a supporting leg 6 form a unitary body, the device is fixed to the conduit line 16. Thus accelerometers 7-9 are operated.
